One instrument contains everything you need to observe multiple signals on analog/logic mixed circuits: DL7440: 4 analog channels and 16-bit logic input (optional) DL7480: 8 analog channels and 16-bit logic input (optional) The DL7400 Series includes 8-channel analog input models in addition to 4-channel models, in a package that is nearly the same size as older models (the DL7100 and DL7200). These new models still have 16-bit logic inputs, which were a popular feature in older models. In addition to multipoint logic signal measurements, the DL7400 Series lets you simultaneously measure analog signals on 4 or more channels without needing to synchronize two separate oscilloscopes. The DL7440 and DL7480 SignalExplorer are designed for users who want an easy, efficient solution in one unit for handling measurements that required two or more units in the past.

Large Recording Memory and Quick Zoom for Accurate Waveform Capturing and Monitoring Even some oscilloscopes with high sampling rates may not be able to accurately capture waveforms if the memory size is not large enough for the required monitoring period. This limitation is due to the necessary drop in sampling rate, which occurs if the recording memory is not long enough. A larger recording memory not only increases the monitoring time, but also enables users to maintain a high sampling rate thus ensuring accurate waveform monitoring. In addition, the zoom function can be used to view enlarged images on one or two segments of a waveform captured in the large memory.

All-Points Display and Fast Screen Updates Make Sure You Won’t Miss Abnormal Signals When working with data captured in the large recording memory, the amount of information appearing on the display varies greatly depending on how the data are presented. The differences occur depending on whether you choose to display all points in a captured waveform, or just major values, such as maximum and minimum values, in a given segment on the waveform. The DL7400 Series provides fast screen updating in allpoints display mode, so you won’t miss abnormal phenomena or have slow responses to instrument controls.

When an abnormal signal is displayed on the screen, does it disappear before you can press the STOP key? History Memory The history memory function divides the large recording memory into a number of blocks and automatically saves up to 4096 previously captured waveforms. You can increase the number of screens that can be saved to history memory by setting a shorter record length.
History Search
History Statistics
The history search function is useful for quickly finding abnormal waveforms in the large amounts of waveform data stored in history memory. This function lets you automatically search for desired waveforms based on whether or not a signal passes through a user-defined area on the screen. You can also conduct searches based on waveform parameters.
Calculates statistical information based on the parameter values for waveforms stored in history memory. This function calculates and displays a parameter’s maximum value, minimum value, average value, and standard deviation. You can check the parameters for every waveform in history memory. Waveform 1

How can I quickly count a large number of pulses in a waveform?
Measuring Periodically Fluctuating Amplitudes Cycle Statistics
Pulse Count
Automatically calculates the maximum value, minimum value, average value, and standard deviation of selected waveform parameters for each period of a signal. You can even find the period corresponding to the calculated maximum and minimum values and display that period in the zoom window. In some applications, like with a PWM (pulse width modulation) Example Applications control signal, you may need to • Amplitude, period, and duty ratio for each determine information about period in various modulation signals each waveform period for long • Current, voltage, and period for each amounts of time. The DL7400 switching cycle as the load fluctuates in Series with its long memory, a switching power supply lets you analyze a long • Each signal level in clock-synchronized waveform, period-by-period, CCD output • Output level of each sensor per revolution based on the period of a reference signal. in engine or motor
Automatically counts the number of pulses in the waveform data between cursors. The threshold level for recognizing a single pulse is user-definable, so you can reliably compute pulses even in signals with unstable levels. With the DL7400 Series, you’ll never again have to manually count pulses on screen or on a stack of printouts.
Example Applications • • • •
Stepping motor revolution pulses Optical disk tracking error signals Interrupt signals from microcontrollers Clock count in serial data
When I want to analyze serial bus data, do I count the “LHHLH…” pattern on the screen, or should I use a separate measuring instrument? Serial Peripheral Interface (SPI) Analysis Function The DL7400 Series has a SPI bus analysis function. SPI is a popular bus for IC-to-IC communications. • Waveform and Analysis Result Display Lists Data 1, Data 2, and CS (Chip Select) simultaneously with the waveform. When you select a data string on the list with the cursor, the corresponding frame is shown in the zoom window. • Data Search Automatically searches through the captured data and finds a data pattern that matches the specified criteria. The SPI data search function will automatically find the user-defined data length and data pattern. • Analysis Settings Connect the individual signals to input channels. You can specify two or more Chip Select (CS) signals for multi-slave SPI analyses (analysis can also be done without CS). CH1: Clock CH2: Data 1 CH3: Data 2 CH4–CH8 and PodA (8 bit): CS

Detects an area in the data matching a user-defined pattern (up to 64 bits in length) and displays it in the zoom window. Searches may be done based on time instead of a synchronization clock.
Simple and Enhanced Triggers The many trigger types in the DL7400 Series enable stable monitoring of a wide range of waveforms. Edge trigger : Triggers activate on a rising or falling edge. A → B (N) : Triggers activate when condition B is satisfied N times after condition A has been satisfied. A Delay B : Triggers activate when the first condition B is satisfied a set length of time after condition A has been satisfied. Pattern : Separate trigger conditions are set for each channel. Triggers activate when the combination of trigger conditions is satisfied at an edge of the clock channel signal. Width : Triggers activate when a comparison of the input pulse width and a specified time width satisfies a condition. (Pulse > Time; Pulse < Time; T1 < Pulse < T2; Time Out) OR : Triggers activate when one or more of the specified trigger conditions are satisfied. TV : NTSC, PAL, SECAM, HDTV (8 types) Logic : Triggers activate when the specified combination of the H, L, or "Don't care" conditions for 16 POD A and B signals is satisfied (optional).
Ethernet
User-Defined Math (with the / G2 option)
Web Server With an Ethernet connection, you can perform various functions using Internet Explorer. • FTP Easily copy and paste files from the internal storage device in the DL7400 Series. This internal storage device functions as one of your PC file servers. • Data Capture Pe r fo r m a c t i o n s such as waveform monitoring, uploading settings, and star ting/stopping measurements.
The DL7440 and DL7480 include addition, subtraction, multiplication, binary conversion, inversion, differentiation, integration, and power spectrum as standard calculation functions. With the optional user-defined calculations, you can define equations using arithmetic calculations as well as a variety of other functions, including trigonometric functions, differentials, integrals, square roots, digital filters, six different FFT functions, and pulse width calculations. In addition, calculation results can be specified as parameters for other equations, so the DL7440 and DL7480 can directly handle complex computations that formerly required data to be uploaded to a PC for computation.
USB
• Measurement Trend Automatically opens Excel, then periodically downloads waveform parame t e r va l u e s a n d graphs them. Easily monitor parameter trends during extended-period measurements.
Peripheral Device Connections
• The DL7400 Series can be completely controlled using a USB mouse. • File names can be entered using a USB keyboard. • Connect a USB printer for color printouts.
PC Connection You can create a PC program to remotely control your DL7400 Series through a PC, similar to remote control operations through a GP-IB interface.
